FILE-CASE.

SPECIFICATION forming part of Letters Patent No. 361,852, dated April26, 1887.

Application filed October 28, 1886. Serial No. 217,422. (No model.)

To all whom/it may concern:

Be it known that I, FRANK R. ALDERMAN, of Detroit, in the county of\Vayne and State of Michigan, have invented new and useful Improvementsin File-Cases; and I do hereby declare that the following is afull,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements inletter-files.

' The object of this invention is to construct a file wherein letters,invoices, or other papers can be readily alphabetically filed away, andfrom which the papers cannot accidentally fall out in moving the casefrom place to place.

To-this end the invention consists of a suitable threesided and bottomedcase provided with a retaining spring clamp or bail at the open side ofthecase for'holdingthe file-leaves and papers within the case all asmore fully hereinafter set forth.

Figure 1 is a perspective View of my improved file-case with thespring-clamp opened. Fig. 2 is a vertical cross-section with clampspringclosed and holding file'sheets in position. Fig. 3 is a perspective viewof one of the filesheetsr In the accompanyingdrawings, which form a partof this specification,A represents a filecase having the three sides a,a, and b and bottom 0.

B are coil or other suitable springs,inclosed and secured within theends of the sides a at the open side of the case, the outer ends of suchsprings being secured to the arms (I of the clamp-bail O, which latteris pivotally secured to the bottom a, as is clearly shown in Fig. 1. Theaction of the springs B is such as to keep the clamp-bail Gin either itsopen or closed position.

At or about the center of the side I) of the case is formed a verticalsemicircular recess, 6, in whichis secured a pin, D, designed to engagewith the elongated slotsf, formed in the tags g of the alphabeticalfile-leaves E. By this construction it will readily be seen that thealphabetical leaves being hung upon the pin D, they cannot possibly fallout of position, and that the letters or other papers placed betweenthem are held in place by the action of clamp-bail 0. Should the tile bevery full and the filed papers beinclined to fall out, they could not sodo, as they would strike against the side arms of the clamp and by thembe retained in place.

The elongated openings in the tags of the fileleaves enable them to beturned up sufficiently to allow of the examination of papers filedbelowwithout the necessity of removing any of them.

What I claim as my invention is 1. The combination, with the box havingopen side, ot'a bail formed of a single piece of wire pivotally securednear its ends to the bottom of said box, and provided with arms (1, andthe springs B, attached at one end to said arms and at the other to thecase,substantially as described.

2. The combination, with the box having recessed sides a, of theclamp-bail 0, formed of asingle piece of wire pivotally secured near itsends to the front edge of the bottom of said box,and having formedintegral therewith the arms d, and the springs B, secured within therecesses in the sides a, and connected with said arms, substantially asand for the'purpose specified.
